BP531 Fractal is tiled by three smaller copies of itself vs. fractal is tiled by five smaller copies of itself.
(edit; present; nest [left/right]; search; history)
COMMENTS

More specifically, all left examples shown in this Problem have Hausdorff dimension log2(3) while all right examples have Hausdorff dimension log3(5).


Left examples can tile themselves by any power of 3 smaller same-sized copies of themselves while right examples can tile themselves by any power of 5 smaller same-sized copies of themselves.


Homage to Bongard's original three versus five Problems.

There are always three groups.

This problem is related to the card game Set.
